SPECIFICA T'ION forming part of Letters Patent No. 265,679, datedOctober 10, 1882.. Application ma; July/10, 1882. (1101101.)

To all whom it may concern:

Be it known that 1, WILLIAM Knu'rzson, of Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Band-Compressing Machines; and I do hereby declare thefollowing to be a full, clear, and exactdescription of the same,reference being had to the accompanying drawings, forming part of thisspecifibation, in which-.

Fignres l and 2 are respectively front and end elevations of a machineembodying my the same with a portion of the casing broken away. Fig. 4is alongitudinal vertical section taken on the liney 3 Fig. 1. Figs. 5to 10 are detail views of variousparts of themachine.

the uncompressed band upon it; and Fig. 12 is a similar view of Y afinished hub.

Similar letters of reference in the several figures denote the sameparts.

My invention relates to improvements in that class of machines employ-edin compressing the metal bands-upon carriage and wagon wheel hubs;audits novelty consists in certain improved. details of constructionandcombinabe hereinafter fully described, and pointed out in thesummaryor claims at the endof this specification.

In the accompanying drawings, A represents the main frame of themachine, B is an annular head or stock, secured rigidly by screws (Torotherwise to the frame A, and having a series of radial grooves, inwhich are dies, D. Eachof these dies consists of a meta block, b,- of awidth adapting it to fit accurately within b I), mounted loosely uponpins 1)" b,,projectin g upward from the block, as shown in Fig. 7, and asmall spring, b of a spiral or other form, recessed into the proximatefaces of the jaws and operating to keep thejaws pressed apart, as shownin Fig. 6. Thejaws b 1) restupon the inner shallower portion of theblock, and their upper faces preferably lie flush with the deeperportion of the block, as shown in that of the block.

' Fig.4, while their combined width, when closed together, as shown inFig. 3, is equal, only to The upper portions of the radial grooves areslightly enlarged, so as 110- permit the jaws to spread apart slightlywhen 'slid outward, as shown in Fig. 6, and the sides 3 of the jaws'attheir inner ends are beveled ofi, as shown in Fig. 6, so that whenthedies are ,fgrced inward their jaws will all close and fit,

against each other, so asto form a complete.

unbroken circle, as shown in Fig. 3. The under face of the outerportionv of e'ach block is provided with a cam-groove, b (shown in Figs.

4, 6, and 7,) and with the cam-grooveof each block one of a series ofstuds or pins, e,on the upper side of a large semi-rotating ring, E, isadapted to engage, as shown in Figs. Land 6.

This'l ring Efis suitablyrecessedinto the frame" vA, so as. to beproperlyguided andheld to its bearings, while being turned. It .isprovided with a series of rollers, E, against which the outer ends ofthe die-blocks are adapted to crank-shaft being inclosed in one'of thehollow standards Ahof the frame and havi'ngitslower s end resting inasnitable step, I, at the-base of the machine, as shown-in Fig. 4,

Monnted upon the shaftHso as to turn freely thereon isa gear-wheel, J,with the teeth of which meshesan endless screw or worm on acounter-shaft, K, (shown in-Figs. 4 and 5,) said counter-shaft being,driven by means of a belt applied to a pulley, L, secured to itsouterend,

.or in any other suitable manner. Also'inonnn 9'0 ed upon the shaft H,above the gear-wheel J, is I a gravitating toothed clutch, ,M; (shown inFigs. 4 and. 8,) which is adapted, when free, to engage with the toothedhub'of the gear-wheel. A verticalgroove, m, is formed in the inner wallof the clutch, and into this groove extends a pin or stud, h, projectingfrom the shaft H,

as shown in Figs. 4 and 8. .From this con- 1 struction it follows thatwhen the clutch is engaged with the hub of thegear-wheel and the moclutch is rotated, the spring-pin presses against the periphery of theclutch until the upperend rotation of the shaft, though the gear-wheelupon the 'h ub and again become an gagefd there;

- metal ring and compress it solidly within the as the dies are drawnback by the continuer tinuing then to revolve, the clutch, riding on thepin in its slot, is gradually caused to rise on the shaft until finallyit becomes entirely latter is rotated the shaft will be likewiserotated, but when the clutch is raised so as to disconnect it fromthehnb the motion of the shaft; will be arrested, The clutch is furtherprovidedwith an internal spiral g roove,o, with which a slidingspring-seated pin, P, is adapted to engage. The side of pin P istoothed, and a pinion, it, on a vertical shaft, S. meshes into theseteeth. A hand-lever, T, is secured to the-upper end of shaft S, and whenturned in one direction it rotates the shaftand causes the pinion toretract the spring-pin, but when released the spring-pin is projectedforward against the clutch, either inside or outsideof the groove 0',according to the position of the clutch. When the clutch and hub areengaged, as shown in Figs. 4 and 8,and the of the spiral slot comesopposite it, and then the pin projects itself within the slot.0ondisengaged from the hub, thus arresting the continues to rotate..Upon the retraction of the spring-pin by a movement of the handlever Tit will withdraw once more from the slot and permit the clutch to fallby gravity with and set in motion the shaft.

A description of the operation of the machine in compressing bands uponhubs will now be readily understood. y

The grooved hub,with the metal bands placed loosely over the grooves, asshown in Fig. 11, is setonend upon an adjustable rest,U, (showrr in Fig.4,) with the uppermost band opposite the ends of the. jaws of the dies.Motion is then imparted to the counter-shaft K, and the gear-wheel J iscaused to slowly turn upon the shaft, H. Upon the spring-pin being nowretracted, so as to permit the gravitatin g clutch to drop and engagewith the hub, the shaft H will in turn be set in motion. As it revolvesthe wrist h will force the slide G inward and laterally, thereby causinga partial rotation of thering E in one direction. This rotation of thering causes its pins or studs 0 to operate in the cam-grooves bfofthedie-blocks and move the dies forward, while at the same time therollers E, coming in contact with the rounded outer ends of thedie-blocks, operate to force the dies forward, causing the ends of thejaws I). b to close with great pressure upon the groove-of'the hub. Thecontinued rotation of the shaft then causes the slide to rotate therlngE back again, and the studs e draw the dies outward into their firstposition, their jaws opening by the action of thesprings during suchoperation,- as shown in Fig. 6. At the time the dies have fully closedin upon the bandithe' spring-pin P is projected within the spiralgroovee in the clutch, and consequently rotation of the shaft H theclutch is gradually lifted out of engagement with the hub of thegear-wheel, and unless the spring-pin is with.

drawn-from the slot, so as to'allow the clutch 'full engagement with thehub, and this, without allowing the clutch to disengage, sets themachine for operation upon that band also.

The bands employed in connection with this machine are preferably of theform and construction shown in another application for a patent filedand now pending. 'After being applied to the hub the bands are turnedoft flush with the surface of the wood, as shown in Fig. 11.

I claim as my .invention 1. In a band-compressing machine, the com-'bination of arest for the hub,-the radiallygrooved head, theradially-moving dies the: ein, and the semi-rotating ring having therollers or cams for simultaneously forcing the dies inward,substantially as described.
